Client control system for routine task

Abstract

A client control system for electronically performing a routine task and for centralized data management in a wide area network (WAN) includes a server, for performing routine tasks; a user-band control unit, including an input / output managing unit, for conducting input / output processing of a user-input form, capable of being displayed in a plurality of modes on a screen; a keyboard for user-supplied data input; a printer for printing an object datum, having a plurality of elements, which is to be input / output processed and registered and managed in a server; and a data exchange control unit for exchanging data and processing a request and a response by and between a user and the server, for controlling the user request by cache control. Response processing is separated into an input / output definition command, and a datum definition command. The user control unit includes an object data-managing unit for sharing and managing the object datum.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a client control system for routine task in a wide area network for managing data in a centralized manner by means of a server and in particular to a client control system for routine task which enables client processing having an excellent response to various input / output processing without requiring any individual maintenance loads. [0003] 2. Description of the Prior Art [0004] A world wide web (WWW) system is known as a wide area network system for managing data in a centralized manner by means of a server. The WWW system is excellent in information sharing and is suitable for centralized management of information. [0005] When the WWW is applied to the routine task processing which is mainly conducted by the input of the clients in a wide area network, it is disadvantageous in the ease of operation since the rate of the communication line between the server and the clients is a bo...

AI Technical Summary

Benefits of technology

[0008] It is an object of the present invention to provide a client control system for routine task in a wide area network for managing data in a centralized manner by means of a server, which enables client processing having an excellent response to various input / output processing without requiring individual maintenance load.

[0010] The client control system for the routine task is formed so that cache control is enabled by separating the processing response from the server into an input / output definition command and a data definition command. Accordingly, the input / output definition command which is repetitive when the client control unit conducts processing based upon the processing response can be obtained from the cache. Communication with server can be minimized so that response of processing of the routine task can be assured even if using a low rate communication line. Since the object data management unit shares and manages the object data for each item in response to various data definition commands and the input / output managing unit conducts the input / output processing of the object data in response to the input / output definition command, input definition of various indication modes which are common in the object data is made possible. The input / output processing in various modes can be conducted on the side of client.

[0012] The client control unit includes the dependence relation managing unit for rearranging the operation order depending upon the dependence relationship between the data items based upon the operation definition. Operation processing can be efficiently conducted by forming the object data operating unit so that it conducts the operation in accordance with the rearranged order. Accordingly, the response of input / output processing for addition and update can be assured.

Problems solved by technology

When the WWW is applied to the routine task processing which is mainly conducted by the input of the clients in a wide area network, it is disadvantageous in the ease of operation since the rate of the communication line between the server and the clients is a bottleneck.

The WWW system is inevitably disadvantageous since considerable cost for facility for the high rate line is required in order to compensate for the low rate of the communication line.

However, the above-mentioned network system requires maintenance for individual task processing software which is distributed to clients since it is necessary to provide task processing software which is relevant to a lot of clients which are in different circumstances.

Accordingly, in a large scale wide area network, a problem occurs in that large load of maintenance is inevitable in the whole of the network.
